Industrial Ethernet Connectivity.
Deployed across 20+ countries.
Industrial Single Pair Ethernet Solutions
A complete portfolio of SPE switches, converters, controllers, and field devices built as a unified system. Engineered for deterministic performance, simplified deployment, and secure connectivity -- from sensor to the cloud.

SPE switches with different IEC 63171 and screw-terminal connectors. IEEE 802.3cg compliant, DIN-rail mounted, and rated from −40 to +70 °C.

PoDL/SPoE power controllers that work alongside Zemfyre switches to deliver IEEE 802.3cg power across all SPE ports. Autonomous operation with CAN Bus telemetry and SCCP device classification.

Bridge SPE 10BASE-T1L to standard RJ45 Ethernet. Options range from compact single-port converters to dual-channel DIN-rail units with PoDL input, PoE output, and link fault pass-through.

Edge devices powered over PoDL on the same wire pair that carries data. Environmental sensing and video surveillance up to 1,000 m from the switch — no local power supply needed.
End-to-end Ethernet Connectivity
SPE delivers data & power over a single pair.
Made in Canada, deployed globally.
Zemfyre develops and manufactures advanced industrial Ethernet solutions, enabling end-to-end connectivity using Single Pair Ethernet (SPE).
